What kind of tournaments are you thinking about entering? There are local events--city, county, tournament clubs. These are mostly handicap events and are for bowlers of all abilities. Then there are house tournaments--six-gamers, eight-gamers, doubles, etc. Some of these are scratch, others handicap. Some of them are so large they attract bowlers from other states (Hoinke, Lilac) Again, if they're handicap, they're for anyone. If they're scratch, then if you see the posted results, you'll see what types of scores are needed to win. Finally, if you are talking about PBA regionals, you would have to follow the PBA guidelines which currently require a 190 average, but in order to do well would require an average much higher than that.
